Convert sympy expression to CasADi

sympy2casadi

def sympy2casadi(sympy_expr,sympy_var,casadi_var):

import sympy
x,y = sympy.symbols("x y")
import casadi
X = casadi.SX.sym("x")
Y = casadi.SX.sym("y")

xy = sympy.Matrix([x,y])
e = sympy.Matrix([x*sympy.sqrt(y),sympy.sin(x+y),abs(x-y)])
XY = casadi.vertcat(X,Y)

Hello!
I run it and added sympy2casadi(e, xy, XY)at the end to check the result. I got a syntax error that could be solved by switching the order in the lambdify arguments to lambdify(sympy_var,sympy_expr,modules=[mapping, casadi]), because according to the Lambdify docstring:

lambdify(
    args,
    expr,
    modules=None,
    printer=None,
    use_imps=True,
    dummify=False,
)

I have noticed that in the second revision you made the inverse change. I am curious about why did you do that?
I am using Sympy 1.4

Thank you and have a nice day

is there any support for casadi to sympy?
